1-Ethyl-3-methyl-quinoxalin-2(1H)-one.

ABSTRACT: The asymmetric unit of the title compound, C(11)H(12)N(2)O, contains two independent mol-ecules. In the crystal structure, inter-molecular C-H?O hydrogen bonds link the mol-ecules. There are ?-? contacts between the quinoxaline rings [centroid-centroid distances = 3.446?(2), 3.665?(2), 3.645?(3) and 3.815?(3)?Å]. There also exist C-H?? contacts between the methyl groups and the quinoxaline rings.

The asymmetric unit of the title compound, C(11)H(12)N(2)O, contains two independent mol-ecules. In the crystal structure, inter-molecular C-H⋯O hydrogen bonds link the mol-ecules. There are π-π contacts between the quinoxaline rings [centroid-centroid distances = 3.446 (2), 3.665 (2), 3.645 (3) and 3.815 (3) Å]. There also exist C-H⋯π contacts between the methyl groups and the quinoxaline rings. ...[more]

5-Ethyl-4-methyl-1H-pyrazol-3(2H)-one.

Project description:In the title compound, C(6)H(10)N(2)O, the 2,3-dihydro-1H-pyrazole ring is approximately planar, with a maximum deviation of 0.013?(1)?Å. Pairs of inter-molecular N-H?O hydrogen bonds link neighboring mol-ecules into dimers, generating R(2) (2)(8) ring motifs. These dimers are further linked into two-dimensional arrays parallel to the bc plane by inter-molecular N-H?O hydrogen bonds. The crystal structure is further stabilized by C-H?? inter-actions.

1-Allyl-3-phenyl-quinoxalin-2(1H)-one.

Project description:The title compound, C(17)H(14)N(2)O, crystallizes with two mol-ecules in the asymmetric unit. The dihedral angles between the mean planes of the quinoxaline ring system and the phenyl ring in the two mol-ecules are 38.27?(10) and 37.14?(8)°. In the crystal, ?-stacking along the b axis contributes to the crystal cohesion with an average distance between quinoxaline units of 3.397?(3)?Å. Weak C-H?O interactions also occur.

Crystal structure and Hirshfeld surface analysis of 1-[(1-butyl-1H-1,2,3-triazol-4-yl)meth-yl]-3-methyl-quinoxalin-2(1H)-one.

Project description:The title compound, C16H19N5O, is built up from a planar quinoxalinone ring system linked through a methyl-ene bridge to a 1,2,3-triazole ring, which in turn carries an n-butyl substituent. The triazole ring is inclined by 67.09 (4)° to the quinoxalinone ring plane. In the crystal, the mol-ecules form oblique stacks along the a-axis direction through inter-molecular C-HTrz⋯NTrz (Trz = triazole) hydrogen bonds, and offset π-stacking inter-actions between quinoxalinone rings [centroid-centroid distance = 3.9107 (9) Å] and π-π inter-actions, which are associated pairwise by inversion-related C-HDhydqn⋯π(ring) (Dhydqn = di-hydro-quinoxaline) inter-actions. The Hirshfeld surface analysis of the crystal structure indicates that the most important contributions for the crystal packing are from H⋯H (52.7%), H⋯N/N⋯H (18.9%) and H⋯C/C⋯H (17.0%) inter-actions.

Project description:In the title compound, C(15)H(8)Cl(4)N(2)O, the quinoxaline ring system is almost planar, with a dihedral angle between the benzene and pyrazine rings of 3.1 (2)°.

The crystal packing features inter-molecular N-H⋯O hydrogen bonds and π-π stacking inter-actions, with centroid-centroid distances in the range 3.699 (3)-4.054 (3) Å.

(Z)-4-[(Ethyl-amino)(furan-2-yl)methyl-idene]-3-methyl-1-phenyl-1H-pyrazol-5(4H)-one.

Project description:In the crystal of the title compound, C(17)H(17)N(3)O(2), the mol-ecules exist in the keto-enamine form. The pyrazole ring is oriented at 10.59?(4) and 57.98?(5)° to the phenyl and furyl rings, respectively, and the dihedral angle between phenyl and furyl rings is 73.30?(11)°. An intra-molecular N-H?O hydrogen bond occurs between imino and carbonyl groups. In the crystal, weak C-H?O hydrogen bonds link the mol-ecules into supra-molecular chains along the b axis.

Project description:In the title compound C(14)H(17)N(3)O(2), the dihedral angle between the rings is 16.68?(13)°. Although the compound crystallizes in the keto form, the possibility of keto-enamine-enol-imine tautomerism is explained by a strong intra-molecular N-H?O hydrogen bond.
